导言这次美国免疫工作者协会专题讨论会是网状内皮系统学会(RES)倡议主办的。三年前,美国免疫工作者协会曾组织过一次有关巨噬细胞的专题讨论会。两年前,RES 学会的年会上也组织过类似的讨论会。由于最近对巨噬细胞的广泛研究,并不断有新的发现,人们越来越认识到这类细胞在免疫中的重要功能,所以决定再组织一次专题讨论会。 Introduction The American Society of Immunization Workers Symposium was hosted by the Reticuloendothelial System Society (RES) initiative. Three years ago, the American Society of Immunization Workers organized a symposium on macrophages. Two years ago, a similar seminar was organized at the annual meeting of the RES Society. Due to the recent extensive research on macrophages and the continual new discoveries, people are increasingly aware of the important functions of such cells in immunity and have decided to organize a symposium again.
